Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of bushing failure include increased noise and looseness in the machine's articulation points. If ignored, the wear will accelerate, potentially damaging the mating pin and bore surfaces. Continued operation with a failed bushing can lead to erratic machine control and premature wear on adjacent components.

Installation Tip

Ensure the bore is thoroughly cleaned of all old material and debris before attempting installation. Avoid using excessive force or hammering, which can distort the bushing or damage the housing.

Service Note

Inspect the corresponding pivot pin and the bore of the mating component for wear or damage during bushing replacement.
